Functions of the basic components of PLC?
Basic componets of a plc are: power supply, CPU(central prossesing unit), I/O CARDS ( INPUT/OUTPUT CARDS)
Explain the Input and output limitation of the PLC?
With a PLC the I/O is fixed when you buy it. Smaller stand alone units are hardwired with the exact I/O you are going to have. Even expandable configurations have a fixed input and output memory table. The PLC scans its Boolean algebra logic, constantly and sequentially, and compares that program to the I/O tables' inputs, outputs and relays. Then it makes its' decisions depending on their state.
What is the full name PLC?
Meaning of PLC
How many types of PLC?
there r 16th types of plc ok
What is the plc stages of hero Honda?
proper plc report of hero Honda with graph
What is meant by plc scan time?
PLC Scan Time means plc requires some operating cycle to Plc input verification,Plc output updates and Execution of program.

How do you check input and output in PLC?
You can check the input and output in PLC by using the force command. Through the programming instrument the input can be forced opened or forced closed depending on what the status of the contacts are set to. This can also be done with the output contacts.
One function of a PLC input interface module is to?
PLC's are used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. just about anything can be controlled because PLC's use microprocessors which can be programmed for a variety of tasks.
What is a unitary plc?
A Unitary PLC is a Low Cost PLC used generally in small machines as it has a very low input/output count. Still Need More Info XD
How much an PLC have outputs and inputs maximum?
There are PLC with fixed inputs and outputs. There are modular ones which can be added on with inputs and outputs. So number of input and output of a PLC is actually based on the type of PLC you choose. Different types are available in the market.
What limits the the number of virtual input and output instructions in a PLC ladder logic?
The only thing that limits the number of inputs and output instructions is the size/amount of the PLC memory.

Definition of coil in contactor?
The coil in a "Contactor" is essentially an electromagnetic coil that provides the driving force to close the contacts in a Contactor. When the "Coil" is energized by a lower control voltage usually from some type of controller such as a PLC, the Normally-Open contactor will close or in the oposite case, the Normally-Closed contactor will open.
What would be a good plc project?
I'm assuming here you are referring to a Programmable Logic Controller. PLC's must be accompanied by input sensors and output devices, so you will be limited by those as much as by the PLC. I would get together some input devices - switches, buttons, temperature switches, pressure switches, whatever your PLC will respond to, and play with those for a bit. Similarly, I would find some output devices that your PLC can turn on - relays, motors, lights, etc. and simply get the PLC to turn them on and off. Then I would just start to build up the I/O until you have rather complex logic - for example, "If I press this button AND I close that switch, the light comes on. Then, if the light is on and I press another button, the motor comes on". Playing with that will go much further in helping to learn about PLC's than starting on a specific project. If you need a project, devise some sensor that will detect a car coming into your driveway, and have the PLC turn on a fan that will ring some wind chimes.
How many Input and outputs s7 200 plc have?
s7-200 have 14 inputs and 10 outputs that can be relay or transistors. Check out www tmartis com for affordable plc and modules.
Different types of registers available in plc?
There are five types of registor in PLC,(1)holding registors(2)input registor(3)output registors(4)microprocessor has internal registor(5)CPU's RAM
